示例1:
static void android_view_GLES20Canvas_drawBitmapData(JNIEnv* env, jobject clazz,
jlong rendererPtr, jintArray colors, jint offset, jint stride,
jfloat left, jfloat top, jint width, jint height, jboolean hasAlpha, jlong paintPtr) {
// Note: If hasAlpha is false, kRGB_565_SkColorType will be used, which will
// correct the alphaType to kOpaque_SkAlphaType.
const SkImageInfo info = SkImageInfo::Make(width, height,
hasAlpha ? kN32_SkColorType : kRGB_565_SkColorType,
kPremul_SkAlphaType);
SkBitmap* bitmap = new SkBitmap;
if (!bitmap->allocPixels(info)) {
delete bitmap;
return;
}
if (!GraphicsJNI::SetPixels(env, colors, offset, stride, 0, 0, width, height, *bitmap)) {
delete bitmap;
return;
}
DisplayListRenderer* renderer = reinterpret_cast<DisplayListRenderer*>(rendererPtr);
Paint* paint = reinterpret_cast<Paint*>(paintPtr);
// apply transform directly to canvas, so it affects shaders correctly
renderer->save(SkCanvas::kMatrix_SaveFlag);
renderer->translate(left, top);
renderer->drawBitmapData(bitmap, paint);
renderer->restore();
// Note - bitmap isn't deleted as DisplayListRenderer owns it now
}
